A demat account holds your shares and securities in electronic form, just as a bank account holds money. ATS opens your demat account with CDSL (DP ID 12074300). To invest you need both a trading account (to place buy/sell orders) and a demat account (to hold what you own) — see our beginner guide to opening a demat account and don't forget to register a nominee.
Trading account vs demat account
A trading account is used to place buy and sell orders on the exchange, while a demat account stores the securities you own. You need both to invest in the stock market. ATS is a CDSL depository participant (SEBI Regn. No. IN-DP-CDSL-656-2012); your holdings sit under ATS DP ID 12074300 combined with your unique client (BO) ID.
Moving shares in and out of your demat
- Dematerialise physical certificates: submit a Dematerialisation Request Form (DRF) with the certificates; ATS forwards them to the registrar and the shares are credited once approved.
- Rematerialise: convert electronic holdings back to physical certificates with a Remat Request Form.
- Transfer from another broker: move holdings online via CDSL easiest or a physical Delivery Instruction Slip (DIS).
Demat charges & statements
